Question

Juhi sells a washing machine for rupees 13,500. she losses 20℅ in the bargain. what was the price at which she bought it.

Answer 1

Let, the C.P. be 't'

∴ 20% of 't' = t× 20/100

                   = t/5

∴S.P. = t-t/5

         = (5t-t)/5

        = 4t/5

By condition,

4t/5 = 13500

⇒ 4t = 13500×5

⇒ t = 67500/4

⇒ t = 16875

∴ She bought it by ₹16875

Answer 2

Step-by-step explanation:

Let, the C.P. be 't'

∴ 20% of 't' = t× 20/100

                  = t/5

∴S.P. = t-t/5

        = (5t-t)/5

       = 4t/5

By condition,

4t/5 = 13500

⇒ 4t = 13500×5

⇒ t = 67500/4

⇒ t = 16875

∴ She bought it by ₹16875
